- This wound interface/liquid retention combination can take many forms including pillows, tubes, self-contained tubular structures and similar structures where the liquid collector can be enveloped in the wound interface. These structures are flexible and can be formed into a suitable shape to fit any kind of wound cavity. Alternatively, several of these pouches can be linked together or otherwise combined to form structures that can be inserted into a deep wound tunnel or deep wound cavity. For example, a linked tubular chain can be formed that can be inserted within a wound tunnel such that the entire wound cavity is filled with this chained structure. A flexible barrier housing material such as Tegaderm can then be used to cover the wound site and seal on the skin around the wound site. The module containing the vacuum source is attached to the flexible barrier housing to create vacuum within the wound cavity. Wound exudate enters the inside of the pouch through the permeable outer wound interface cover and gets absorbed within the liquid collector. As before, the liquid collector will permit application of vacuum to the wound while absorbing and retaining liquid drawn out of the wound.

- the vacuum disperser may also be a hydrophobic structure positioned at the inlet of negative pressure into the housing 1220 . It will be appreciated by those of skill in the art that the vacuum disperser may preclude the occlusion of the inlet by liquid collector material.
- the retention chamber 1240 and/or the liquid collector 1242 may be single or multi layered.
- it may be composed of the liquid collector 1242 , the vacuum disperser 1282 and the moisture disperser 1280 . These layers may be present between the liquid collector 1242 and the liquid barrier 1236 (or vacuum chamber 1224 ) or between the absorption layer 1242 and the wound bed.
- the disclosed devices and their methods of use may be useful for the therapy of surface wounds on a patient.
- wounds may include, but are not limited to, infectious wounds, burn wounds, venous and arterial ulcers, diabetic ulcers and wounds, post-surgical wounds, bed sore wounds, and the like. Additionally, such devices are contemplated for use in a variety of fields, as would be contemplated by one of ordinary skill in the art.
- a device having a housing with a liquid-retention chamber is positioned above at least a portion of the wound. Negative pressure may be applied to the wound using the vacuum source. Wound liquids or exudate may be collected in the liquid-retention chamber. Additionally, the device may be replaced when it is filled with liquid. In modular embodiments, the liquid-retention chamber module, wound interface module, or the vacuum source may be replaced separately or in combination as needed.
- a method of assembling a wound therapy device includes the steps of providing a vacuum source module comprising a vacuum source capable of generating negative pressure and a pressure controller for controlling the amount of negative pressure.
- the method also includes providing a dressing module having a housing to cover at least a portion of a wound site.
- the dressing module also includes a porous liquid collector positioned within the housing and in communication with the wound site.
- the liquid collector is configured to retain wound exudate while simultaneously communicating negative pressure generated by the vacuum source module to the wound site.
- the dressing module may also include a liquid barrier positioned between the liquid collector and the vacuum source module.
- the dressing module may further include a seal for sealing the dressing module to a surface around the wound site.
- the method includes securing the vacuum source module to the dressing module, such that the vacuum source module transfers negative pressure to the dressing module and attaching the device adjacent a wound site. It will be appreciated by those of skill in the art that the method steps may be practiced in a number of different orders to practice the teachings of the invention.
- the devices may be adapted to be inexpensive, light-weight, and either partially or entirely disposable. Further, the devices may be adapted to be simple to operate, such that in some instances, a patient could place the device with some reduced degree of medical supervision. In addition to the above, the devices may be constructed so as to be used without attention to their orientation.
- the devices may take a variety of forms, including those that are completely disposable when full, or partially disposable such as, for example, either the vacuum source or the liquid-retention chamber.
- the entire device may be discarded and replaced when filled. This may be convenient for smaller wounds, wounds that are already well along in the healing process, and wounds that are under home care. Such methods and apparatus prevent and/or reduce contact with potentially contagious or dangerous bodily liquids.
- the housings disclosed have been illustrated in particular shapes, such as being generally rounded, the housings are not necessarily limited to particular shape, and may be constructed in any advantageous shape.
- the devices may be sized and shaped such that the vacuum chamber or liquid-retention chamber is capable of sealing over the patient's wound, at least in part.
- the housings and the seals disclosed may be configured to hold a vacuum when the device is placed and sealed over at least a portion of a wound on a patient's body surface. Such seals may be substantially air-tight to prevent the entry of microbes but do not need to be absolutely impermeable. It is contemplated that vacuum pressure will either be continuously or periodically applied to maintain a therapeutic negative pressure therapy range.
- the devices When the vacuum is switched on after placing the device on a patient's wound, air is removed around the wound, generating a vacuum within the housing cavity. At the same time, wound-liquid absorbing material may begin absorbing the exudate/liquids in the wound. Sustained negative pressure over a wound region may promote tissue migration and wound closure.
- the devices may be shaped like a patch or bandage that may be changed more than once a day. It will be appreciated by those of skill in the art that the device may continue to absorb and trap fluid when the device or vacuum is switched off.
- the device may contain a fill indicator that senses the presence of free moisture in the liquid-retention chamber that signals that the optional porous pad has reached a predetermined absorptive level.
- the fill indicator may in turn be coupled to an over-flow valve to prevent wound liquids from reaching the vacuum pump or it may provide a signal used to prompt disabling the pump.
- the devices when the devices are adapted to be disposable, they may be discarded after use in part or in whole. Indeed multiple disposable devices can be provided to a patient for a treatment plan, which may consist of a plurality of individual treatments with disposable devices over a predetermined period.
